Nano-silicon/reduced graphene oxide composite anodes for high performance all solid-state batteries

Abstract

Nano-Si (n-Si) encapsulated with SiO_x shells and anchored onto reduced graphene oxide (rGO) via hydrothermal self-assembly is demonstrated as a promising solid-state battery anode. Compared to simple n-Si, this composite anode exhibited improved rate capability and cycle life, enabled by robust Si–O–C bonding, mechanical reinforcement, and rapid electron transport.
